摘要

In the course of the Fukushima nuclear accident large amounts of radionuclides relevant to the Comprehensive Nuclear-Test-Ban-Treaty (CTBT) were released and detected globally. We could show that the intake of environmental ~(131)I into the thyroids of animals can be used for verification of the CTBT. Due to continuous accumulation of ~(131)I, its apparent half-life in the thyroid biomonitor exceeds the physical one, thus making ~(131)I detectable three weeks longer than using conventional CTBT-grade high volume air samplers. The maximum ~(131)I activity concentrations (in Bq/kg) found in Austrian animal thyroids after the Fukushima nuclear accident could be correlated with the maximum activity concentrations found in air (Bq/m~3) in Austria via a factor of 1.1 × 10~6. In fall 2011, a second (much smaller) release of ~(131)I occurred from a laboratory in Hungary, where this factor was 1.9 × 10~6. Hence thyroid biomonitors offer even some quantitative information, which allows the estimation of the~(131)I activity concentrations in air. It could be shown that thyroid biomonitors can work under dry conditions, which potentially makes them the method of choice for CTBTO on-site inspections even in arid environments.
